pbm with default icon replaced by generic icon

Hi everybody,

(I posted a similar message on a Word NG, but I now feel it could be a pbm
with Vista.

for some reason my Word shortcut icon has gone and has been replaced with
the Windows generic icon. I tried to suppress this shortcut and recreate
another one, to no avail. To do this I did Start > Programs > Microsot
Office > MS Word 2007 >> Right click > Send to > Desktop (Create a
shortcut).

Doing this I create a shortcut with the generic icon, not the original,
default Word 2007 icon.

I also tried to right click on this shortcut > Properties but the "change
icon" button is greyed.

Interestingly, If I create an icon from the Winword file in Program files, I
do get a proper icon, with the label "shortcut to ...".

In other words, it seems that the problem only affects, as far as I know,
the Word shortcut icon created from the Start > Programs menu.

The icon in the quick launch bar is OK. The icons associated with the word
documents in Explorer are OK.

If I copy the icon in the quick launch bar onto the desktop, the default
Word icon is replaced with the generic one.

and of course I cannot correlate this new problem with anything I could have
done, except, may be, rearranging all my icons on the desktop after they had
been "reshuffled" for some reason (this happens now and again).

How can I recuperate the original MS Word icon?

I have Vista Ultimate and Office 2007.

Many thks for your kind help.

Brgds
Daniel
